Connecting structure of small flue and waste-gas opening and closing device

Abstract

The invention relates to a connecting structure of a small flue and a waste-gas opening and closing device. The connecting structure is characterized in that a partitioning wall is arranged in the small flue and partitions the small flue into two branched flues; the connecting structure comprises a small-flue connecting pipe, a partitioning plate and an inserting plate; one end of the small-flue connecting pipe is connected with the small flue, and the other end of the small-flue connecting pipe is connected with the waste-gas opening and closing device; one side of the small-flue connecting pipe, close to the small flue, is provided with the partitioning plate along the longitudinal direction; one end of the partitioning plate is connected with the partitioning wall in the small flue, andthe small-flue connecting pipe is partitioned into a connecting channel I and a connecting channel II; one side of the small-flue connecting pipe, close to the small flue, is provided with an inserting plate along the horizontal direction; the inserting plate can close the connecting channel I or the connecting channel II partially or wholly. The connecting structure has the beneficial effects that the partitioning plate and the inserting plate are arranged on the small-flue connecting pipe and are matched with the small flue with the partitioning wall for use, so that adjustment of the flue-gas flow area is realized and the production need of a top-mounted tamping integrated coke furnace is met.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a connection structure between a small flue with an adjustable flue gas flow area and a waste gas shutter. Background technique [0002] At present, the newly developed top-loading and tamping dual-purpose coke oven can use two different processes for coke production, either top-loading or tamping. Because of its better adaptability, it has become a research hotspot in the coking field. In the design process of top-loading and tamping dual-purpose coke ovens, considering the timing of top-loading coking and the large temperature difference of the standard flue on the coke side, the timing of tamping coking and the small temperature difference of the standard flue on the coke side, the inner edge of each small flue A partition wall is added longitudinally. This partition wall is set from the machine side to the coke side. It divides the small flue into two sub-flues. Each sub-f...

Problems solved by technology

When the top-loading coking process is adopted, the main branch flue and the supplementary branch flue are opened at the same time; when the tamping coking process is adopted, the main branch flue is opened, and the supplementary branch flue is closed; so as to meet the requirements of the top-loading tamping integrated coke oven respectively The different needs of the two coking processes, and realize the rapid switching between the two coking processes; after the structure of the small flue is changed, the traditional small flue connecting pipe with only a single connection function can no longer meet the use requirements
